    摘要： A screen image observing device and method provides the sensations of virtual reality to the observer and reduces, to the extent possible, the discrepancy that is perceived by the observer between the movement of the observer's head and the displayed screen image. The device has a head tracking means, which detects the movement of the observer's head, and a screen image generating means, which generates image data based upon the result of the detection performed by the head tracking means. Image data is supplied to a display means.

    摘要： An overhead projector provides an unobstructed view of projected images by minimizing the vertical dimension of the projector and provides sufficient brightness of projected images by minimizing the loss of light. The light emitted from a light source housed in the body of the projector is reflected by a first reflection mirror and directed, through a transparent stage on which a transparent original is placed, to a second reflection mirror. Meanwhile, on the transparent stage, the principal ray axis of the light beam forms an angle .theta. with respect to the center axis of the surface of the transparent original. After reaching the second reflection mirror and being reflected thereby, the light is condensed into a projection lens unit, and is projected therefrom onto a screen to form thereon an image of the transparent original.

    摘要： A projecting optical device which simultaneously projects one object onto two or more different screens has a first screen, a second screen, a first projecting optical system which projects the object onto the first screen, and a second projecting optical system which projects the object onto the second screen and does not share an optical element with the first projecting optical system. A first base line connecting the center of the object to the center of the image projected on the first screen by the first optical system and a second base line connecting the center of the object to the center of the image projected on the second screen by the second optical system are not parallel to each other.
